Force = mass x g, where g is the acceleration due to gravity (-9.8m/s2)

To find mass, manipulate the equation such that

mass = Force/g = -147N/-9.8m/s2 = 15kg

The force and g are negative because they act in a downward direction.

The mass is in kg because a Newton is a kg*m/s2.

Newtons is a measure of Force.

Newtons first law states Force = Mass times Acceleration

Acceleration due to gravity = 9.81 m.s^-2

Rearranging Newtons First Law, we find Mass = Force divided by Acceleration

So, Mass = 147 / 9.81

Mass = 14.98 kg.

I would round this up to 15kg

Force of a falling object is found by multiplying its mass by acceleration caused by gravity. With the assumption that gravity is 10m/s2, the mass of the falling rock will be 14.7 Kg.

Take 147 N and divide that by 9.8 m/s^2. The answer is 15 kg.

What increases as force increases?

F=ma, or force equals the product of mass and acceleration. Assuming that the mass of the object does not change, then acceleration increases as force increases.


How many newtons of force does a rocket need to take off?

This depends on the weight of the rocket, weight being the mass of the rocket multiplied by earth's gravitational pull. To take off, the rocket needs to exert force larger than the weight, and for a sufficient amount of time to break out of orbit. For instance, if the rocket had a mass of 1kg, it'd exert (1 * 9.8), or 9.8 Newtons of force towards to ground via it's weight (9.8 being the acceleration towards the ground due to gravity). This means that to start to accelerate away from the ground, the rocket would need to exert force higher than 9.8 Newtons. If your hypothetical rocket has a mass of x kg, then it will need to exert a force greater than 9.8x newtons, ignoring air resistance and decaying of the gravitational field.


Is the magnitude of force measured in grams or newtons?

When force is proportional to mass and acceleration why do you say force is proportional to mass multiplied by acceleration why not mass plus acceleration and so on?

By definition, if two things are proportional to one and other, they are connected by a multiplying constant. If F = m + a you would simple say F is a bigger than m and it would also require that force, mass and acceleration all shared the same dimensions and units. Clearly mass is a scalar and force and acceleration are vectors, so that is not the case. Also, if they shared the same dimensions, they would effectively be the same thing so F = m + a would be the same as F(total) = F(1) + F(2) which wouldn't tell us very much about the laws of physics at all. Also, you don't say force is proportional to mass times acceleration (it's EQUAL to mass times acceleration). It's either force is proportional to mass (in which case acceleration is the factor of proportionality) or force is proportional to acceleration (in which case it is mass).


What is the mathematical formula in getting the acceleration mass and force?

Force = Mass x Acceleration Note that the "Force" here refers to the resultant force if there is more than one force acting on the object.

What is the mass of a falling ball if it hits the ground with a force of 5678 N?

Since force = mass x acceleration and the acceleration due to gravity is a constant (9.8 m/s2) you can write an equation plugging in known values to solve for mass. 5678 (force) = m(9.8). Divide both sides by 9.8 to solve for mass, which is 579.38kg

How to prove that normal force is equal to the product of mass and gravity?

The normal force is what prevents an object from falling through the ground. The force of gravity is equal to the product of the mass and acceleration due to gravity, so the ground that the object sits on must apply an equal force in the opposite direction (Newton's Third Law), other wise the object would fall through.


What is the force on a 1000 kilogram elevator that is falling freely under the acceleration of gravity?

Force = mass * acceleration Since the only force acting on the elevator is gravity, the force is 1000*9.81 = 981N Towards the ground Note that it is essential to put the direction that the force is acting as it is a vector quantity.

Why does gravity make falling objects fall faster?

By Newton's Second Law: force = mass x acceleration, or acceleration = force / mass. Since there is a force, there should be an acceleration - a change of velocity.


Why is there no gravity in outter space?

There is gravity everywhere. -- The force of gravity that you feel is a force between you and another mass. The Earth is the "other mass" that we're all used to. If there's no major mass nearby, then there's no force to feel. -- Even if there is a major mass nearby, you don't feel the gravitational forces if you're falling freely toward it. In "outer space", you're falling freely or coasting most of the time, without running your rocket engines. So even if there is some mass that you're being attracted to, you don't feel the force, because you're falling freely toward the mass.

What explains why the earth does not move toward you when you jump in the air?

The Earth has a greater mass than you do. It certainly moves towards you, but much less than you do. This can be explained by Conservation of Momentum, or equivalently, by Newton's Second Laws and Newton's Third Law. (By the Second Law, Earth's force on you is the same as your force on the Earth. By the Third Law, the effect on a larger mass, of the same force, is less.) Technically, as you jump up, the Earth is pushed down; as you come down, the Earth moves up (and meets you). But you weight little and the Earth weighs much more -- so don't expect to see any movement. Besides the Earth is less of a whole than you are. For instance, in a canoe, you jump out to the right. The canoe (and some water -- read "and some of the Earth") move to the left.


How do you calculate force of rain?

You would need the mass of the rain drop(s) you are calculating and since it is falling downwards (not including any interfering forces) it would be falling at a constant acceleration of 9.8ms squared, so using the formula force = mass X acceleration you would be able to get the resultant force


How equation of motion are modified for freely falling objects?

The equation of motion is not modified. Net force = mass x acceleration, whether freely falling or not.
